在 Yii 框架中，如何合并列并在下拉列表中显示为显示字符串

I have a dropDownList in my view, it is populating from clients table, the table contains columns like first_name, last_name,id etc., Now I want to show the first_name and last_name as display text and id as value in drop down list, I'm done with id as value and first_name as display text, but here I want to combine those columns (first_name and last_name) and use as display text.

在模型中

function getClients()
{
    $Clients = Client::model()->findAll();
    $list    = CHtml::listData($Clients , 'client_id', 'first_name');
    return $list;
}

正在查看

echo $form->dropDownList($model,'client_id',$model->getClients());

推荐答案

这是另一种方法在模型中

function getFullName()
{
    return $this->first_name.' '.$this->last_name;
}

function getClients()
{
    $Clients = Client::model()->findAll();
    $list    = CHtml::listData($Clients , 'client_id', 'fullName');
    return $list;
}
